Dan uses a remote control to make his drone take off from the ground. Function h represents the height, in feet, of the drone t

alex41 [277]

Answer: C. The drone is on the ground at 0 and 4 seconds.

Step-by-step explanation:

Here the function that shows the height of the drone,

$h(t) = -16(t-2)^2+64$

Where t is the time in seconds.

Since, the drone is ground when, h(t) = 0

$-16(t-2)^2+64=0$

$-16(t-2)^2 = -64$ (by subtracting 64 from both sides 64)

$(t-2)^2 = 4$ (dividing both sides by -16 )

$t^2-4t+4= 4$

$t^2-4t= 0$ (by subtracting 4 from both sides)

$t(t-4)= 0$

⇒ t = 0 or t = 4

Thus, Option C is correct.

If y varies directly as x and y=12 when x=c what is y in terms of c when x=8

tatiyna

"y varies directly as x" means y = kx

you do not know what k is yet, other than that it is some constant number.

Now plug in the given values, y=12 when x=4, in the equation

12 = 4k

=> k = 3

Now rewrite the equation with the k value you just found

y = 3k

Substitute 18 in place of x

y = 3(18)

y = 54
